Who is responsible for locks in New Brunswick?

Landlords must provide and maintain locks that keep a rental unit reasonably secure. Tenants are responsible for replacing keys they lose or for damage they cause. If a lock failure affects habitability or security the landlord usually must repair or replace the lock at their cost. For questions about enforcement or disputes, the provincial Residential Tenancies Program and Tribunal can hear applications and orders [1]. Refer to the province's tenancy legislation for the legal duties that apply in New Brunswick [2].

In New Brunswick, landlords must keep rental units secure by maintaining locks and doors.

Common situations and who usually pays

  • Worn or faulty exterior locks caused by age or ordinary wear — landlord pays to repair or replace the lock.
  • Lost keys or tenant-caused lockouts — tenant usually pays for replacement keys or lock changes unless the landlord agrees otherwise.
  • Damage from forced entry or vandalism — the responsible party pays; if the cause is unclear, document and report it promptly.
  • Security concerns that require immediate lock changes for safety — the landlord typically arranges and covers costs unless tenant conduct caused the risk.
Documenting the condition of locks and who had keys helps resolve disputes quickly.

For urgent safety repairs and emergency entry situations, see the guidance on Emergency Situations and Repairs: Tenant Rights and Responsibilities and how routine maintenance is handled in rental units in the province at Routine Repairs in Rental Units: Tenant and Landlord Responsibilities. If replacing a lock is a landlord responsibility, ask for written confirmation and a timeline in case you need to file an application with the tribunal [1].

Getting quotes, receipts and approval

Whether you or the landlord arranges the work, keep written quotes and paid receipts. A clear paper trail makes it easier to challenge improper charges or to request reimbursement.

  • Ask the repairer for a written quote before work starts and a detailed receipt after completion.
  • Take photos of the damaged lock or door and keep any text or email exchanges with the landlord.
  • If the landlord asks you to pay, ask for written approval confirming reimbursement terms and timelines.
Detailed documentation increases your chances of success in disputes.

When to contact the Residential Tenancies Tribunal

If you cannot agree with the landlord about who pays, or if repairs that affect security or habitability are not completed within a reasonable time, you may file an application with the Residential Tenancies Tribunal to request an order for repairs or reimbursement [1]. Include quotes, receipts, photos and a log of communications.

FAQ

Who pays if a lock breaks from normal wear and tear?
The landlord is usually responsible for worn or faulty locks because maintaining secure entryways is part of their duty to keep the unit safe and habitable.
Am I responsible if I lose my keys?
Yes, tenants are commonly responsible for replacing lost keys or the cost to rekey a lock, unless the landlord agrees to cover the cost or the loss was caused by the landlord's negligence.
Can a landlord enter my unit to fix a lock?
Landlords may enter to make repairs but must follow notice and entry rules in the tenancy legislation; in emergencies they can enter without prior notice to protect safety or prevent significant damage.

How-To

  1. Contact your landlord or property manager right away, explain the problem and ask if they will arrange and pay for the repair.
  2. Document the issue with photos and written messages, and keep copies of any quotes and receipts you receive.
  3. If the landlord does not act, get one or more written quotes from qualified locksmiths and send them to the landlord with a clear request for action.
  4. If the dispute continues, file an application with the Residential Tenancies Tribunal including all documentation and a request for reimbursement or an order to repair.
